Research On The Impact Of Residential Built Environment On Residents’ Low-carbon Travel

Urbanization has brought the rapid development of urban motorization,and it also brings great convenience and flexibility to people’s travel.However,due to the continuous spread of the city and the rapid growth of motor vehicles,the resulting of traffic congestion,energy waste,environmental pollution problems has become the key problems that our government is currently facing and urgently needing to solve.Compare to the traffic congestion charging strategy and odd-and-even license plate rule,such measures as changing the urban built environment and optimizing the structure of urban space layout and travel to create a low carbon behavior oriented urban built environment,are considered the most effective measures to alleviate urban traffic congestion,environmental pollution and so on the city problem.Those measures can shorten the travel distance of residents and guide residents to take low carbon travel by reducing residents’ s dependence on the car.Based on the hypothesis that "the built environment has different impacts on residents’ low-carbon travel under different travel purposes" and the travel survey data of residents in Panzhihua city,this paper divides the residents’ travel purposes into commuting,living and recreational travel.Firstly,the data of residents’ travel survey were analyzed and preprocessed,and then the model variables were designed and analyzed.Finally,by constructing the analytical framework of Hierarchical Linear Model,the paper studies the impact of built environment on residents’ low-carbon travel under different travel purposes,and draws relevant conclusions and Suggestions for improving the built environment of cities.The research results based on the data of Panzhihua City show that,for commuting,the higher the population density in the residential area,the higher the probability that residents will commute by car.The increase of land use mixing degree and bus station density can effectively improve the probability of residents to choose non-motorized and public transport and other low-carbon transportation modes.After controlling for related variables,the probability of residents choosing public transportation increased by 46.24% and 49.71% for every standard unit increase of land use mix degree and bus station density.According to the research on travel distance,increasing land use mixing degree and strengthening land development intensity can indirectly shorten people’s commuting distance;For living travel,the higher the population density of the residential area,the higher the probability of residents to choose walk and public transportation when they are traveling.The density of bus station has a significant negative effect on residents’ choice of living and traveling modes.All variables of built environment have no significant influence on recreational travel.Based on the above conclusions,the paper finally puts forward Suggestions for urban development and traffic planning,in order to provide theoretical support for urban planning and traffic management departments to launch relevant policies and management measures.
